Влияние на целодневната организация на учебния ден върху учебните постижения по български език на второкласниците

Making the all-day organization of the school day a factor for a quality learning process is an important priority of school policy. Practice shows that when it is well organized, the all-day organization is sought after and desired by parents because it helps to build lasting learning habits and skills, has a positive effect on students' learning achievements, leads to the easier overcoming of educational deficits, and increases the confidence of the students from the primary school stage in the independent performance of set tasks. The determination of the guidelines for its improvement should be based on real information obtained during the diagnosis, which helps to determine the degree of influence of the main factors that affect the learning process. The study and analysis of the impact of the proposed models of all-day organization of the school day on the academic achievements of second-grade students in the Bulgarian language allows the identification of specific measures at school and class level to increase the effectiveness of education, including - education on individual subjects. The formation of basic language literacy is the basis for the acquisition of the key competence of "communication in the mother tongue", building skills for free and successful communication, which supports full personal development. The ongoing assessment of students' learning achievements by the teacher gives important feedback to both students and parents, as well as to the teacher for the effectiveness of his work on learning the content. Practice shows that the optimal daily routine and distribution of the workload in the all-day organization of the school day support and increase this efficiency.

Energetic improvement of smart Healthcare system using Internet of Things

In this modern era, each and every individual needs a global communication without any range and timeline restrictions. A well-known Internet of Things (IoT) provides such support to individuals and organization to provide range free communication services without any hurdles. This paper introduces a new methodology called Healthcare Processing with IoT Surveillance (HPIoTS), in which it adopts some latest technologies to provide an efficient support to monitor the healthcare of the respective patient and report those details properly to the server end with the help of Internet of Things. This proposed scheme of HPIoTS enables a shrewd Healthcare framework in Internet of Things platform, in which it screen a patient fundamental health oriented issues with surrounding atmosphere ratios such as temperature, humidity level, position and so on. In this framework, a smart health assisted gadget is designed with different sensors to catch the health related information from the patients’ side such as: Heart Rate Monitoring Sensor, Pressure Sensor, Temperature and Humidity Level Monitoring Sensor and MEMS Sensor. The association of these sensors made a device more perfect to acquire the health summary of the patients periodically and pushed into the server end without any timing delay and human interventions. The maximum error rate of this proposed approach is estimated around less than 5% as well as this will be proved properly in results sections via graphical proofs. This paper adopts the machine learning strategy to predict the patient health related issues and provides a good accuracy level of 97% in result. The proposed approach guarantees the efficiency of the healthcare monitoring system by using Healthcare Processing with IoT Surveillance (HPIoTS) as well as the resulting accuracy levels are proved on the results section with proper graphical outcomes.

Reinvention of an academic anaesthesiology department during pandemic times: lessons learnt and adapting to a “new normal”

Conditions created by the COVID-19 pandemic have impacted many aspects of medical practice. Responding to this crisis has required health systems to rapidly address a multitude of concerns, including workforce safety, staff redeployment, supply shortages and physical space restructuring. The pace of change created by new information and evolving conditions has proven challenging for traditionally-structured academic departments in medicine. Pandemic medicine requires a nimbleness in decisionmaking, clarity of communication and comprehensiveness of services that may demand a temporary rearrangement of leadership structure and clinical service delivery. Furthermore, the uncertain nature of a pandemic may require reinstitution and dissolution of services as demand sporadically either rises or falls. As the global medical community continues to respond to what may be multiple COVID-19 peaks stretching over months or years, it is important that approaches to preparation and management of the pandemic are shared to enable the identification of best practices and an effective response. With the availability of open access and free communication technologies, these strategies can be easily shared among the global anaesthesia community. The approach outlined here represents one way to organise leadership and streamline communication in order to reinvent an academic department to match the dynamic requirements of crisis conditions. We describe our experience in offering new services such as an airway team, COVID-19 simulation training and personal protective equipment testing, as well as our approach to evaluating the rapid flow of research findings related to SARS-CoV-2 and COVID-19. We summarise lessons learnt and our adaptation to what may be a “new normal” in anaesthesiology practice.

Adult Tetrology of Fallot: A Doppler Echocardiographic Finding

In TOF the morphological abnormalities are – overriding of aorta, pulmonary obstruction, right ventricular hypertrophy and ventricular septal defect. Normally it is nonrestrictive means free communications between the ventricles but sometimes very rarely it can become restrictive when the tricuspid valve restrict the flow across the ventricular septal defect. Among children with CHD 10% of them report TOF. Chest radiographs usually show a normal-size heart silhouette, with an upturned apex and a concave main pulmonary artery segment, commonly known as “boot-shaped” heart. On the electrocardiogram, it is common to see signs of right atrial enlargement and right ventricular hypertrophy showing right axis deviation, prominent R waves anteriorly and S waves posteriorly, upright T wave in V1 (abnormal after 7 days of life up to 10 years of age) and a qR pattern in the right precordial leads. If the ration between pulmonary artery orifice diameter to aortic orifice diameter is <.3 primary repair is unsuccessful and in that case we must go for shunt surgeries which are palliative procedures till permanent repair can be done. This should add proper assessment of coronary artery origin. This is a case of adult tetralogy of fallot (TOF) coming to outpatient department of cardiology with complaints of chest discomfort and sometimes cyanotic spells. Age of the patient is 42 years male. Doppler Echocardiography was done. In the image overriding of aorta was found around 20% over interventricular septum. Left sided aortic arch was detected along with ventricular septal defect (VSD) with size 14 mm. Size of pulmonary orifice 10 mm and that of aortic orifice was 22 mm. Hence pulmonary artery orifice was found to get stenosed.

О СОЦИАЛЬНЫХ ФУНКЦИЯХ ВАРИАНТОВ СЕРБСКОХОРВАТСКОГО ЯЗЫКА

The issue of the status of languages that emerged on the basis of the Serbo-Croatian language after the collapse of Yugoslavia remains relevant until now. The standard Serbo-Croatian language arose in the 19th century as a common language of Serbs, Croats, Bosnians and Montenegrins and existed in two main variants, “western” and “eastern”, from the very outset. These variants were close enough to maintain free communication, and at the same time, each variant had symbolic significance as a marker of the corresponding ethnic group. This article provides an outline of the history of the Serbo-Croatian language from its origin to the collapse of Yugoslavia in the light of two social functions of the language, communicative (language as a means of exchanging information) and symbolic (language as a symbol of national identity).

Farewell to Law and Philosophy: Some Preliminary Explications Abstract.

The modern intellectual situation is characterized by the exhaustion of the possibilities of human existence, and its replacement by technological algorithms. The closest connection of law with the essence of human existence causes the corresponding exhaustion of the possibilities of law and its completion as a discursive form of arrangement of the world. The project of European metaphysics is contradiction between the plurality of the world of things and the meanings of words and the unity and universality of the intangible that exists outside of things – the world of ideas. Dichotomy is localized in the essence of human: the material corresponds to the body, the ideal – the soul. A consequence of this opposition is to assert the metaphysic to eliminate material from the realm of meanings, to deny its significance for human existence. The non-metaphysical position regarding human existence is represented by the sophisticated (poetic) principle of the closest connection of human to things. There is no mechanism for unification and preventing the ambiguity of word meanings. The connection of a particular person with a particular thing always hides the possibility of creating new meaning. Contrary to marginalization of sophistry within the limits of general philosophical discourse, the sophisticated (poetic) principle of connection between human and things became the basis of law. The origin of the latter was ownership right – the closest connection a person has with a thing that constitutes personality and the space of free and equal communication with others. The true meaning of ownership right can be revealed through the concepts of ontological distinction, being-in-theworld, and being appropriated by being human by appropriating things and opening a unique trajectory of personal design. The modern technological picture of the world is a complete and final realization of the metaphysical project of replaces discourse with mathematical algorithms. Human actions are emanating from both the sphere of things and the relations with people. The integrity of the property and the enforceability of the contracts become mathematically secure. The inability to violate a right means its disappearance. The world is no longer a matter of human concern and risk. Things are replaced by objects, and man is destined to become one of them.

Italian Studies and Graffiti, A Complex Relationship

Despite its massive presence in our cities, the accusations of vandalism have caused scholars of Italian language and culture to shy away from the analysis of graffiti. Another factor might also have been a certain traditional elite perspective, to the detriment of ordinariness and of the everyday. In today’s society of widespread control of both physical and virtual spaces through capillary video surveillance and online monitoring which sees the usable spaces for dissent reduced graffiti art still represents an opportunity for free communication. Documenting and studying graffiti means participating in a work of democratization of linguistics, lightening it from the redundant burden of the classics, by the rigid reference to standard Italian compared to popular Italian (intended as a variety of speakers from the lower social classes characterized by poor social prestige), and by a certain purism that translates into fear of those evolutionary dynamics of the language that find representation in graffiti, not by chance creator and diffuser of numerous neologisms and linguistic contact.

Route manipulation aware Software-Defined Networks for effective routing in SDN controlled MANET by Disney Routing Protocol

• The Proposed scheme helps to find the optimal routing with a secure and intelligent manner • Proposed method achieves a better ratio for packet transmission delay • Route manipulation matrix helps to find the intruder free communication toward the different nodes In MANET network management, the Software-Defined Networking (SDN) plays a vital role in terms of controller plane and data plane. It is always easy to manage the data communication over the MANET because of logically centralized control on the SDN. Since the dynamic route on MANET, are controls the packets and changes the route between the source to destination alternatively. Hence the maintenance of real-time SDN analysis-based application planes is a crucial process. To maintain the effective MANET communication over the Software-Defined Network, it essential to improve the control and data plane process on the SDN controlled MANET based OpenFlow switching procedure. Nevertheless, SDN allows for route interaction against security threads. In this research article, the four stages were suggested to preserve the security measures in packet-based data transmission that are conceived in MANET. In this article, an SDN controlled MANET based OpenFlow switching scenario for effective security threading is proposed. The major part played by an SDN controlled MANET in bringing about a result of being effective without wasting time and energy on routing. The proposed Distinct Network Yarning (DISNEY) routing protocol for SDN controlled MANET overcomes the congestion communication on MANET routing. To decrease performance degradation, efficient routing is maintained by the route matrix manipulation table. This routing scheme helps to find the optimal routing with a secure and intelligent manner. The proposed result was compared to existing approaches. As a result, the proposed illustration to be improved by routing and data transmission. In comparison to the proposed method achieves a better ratio for packet transmission delay, throughput, and data transmission rate.

Conical dielectric resonator antenna for terahertz applications

Abstract Conical Terahertz DRA (dielectric resonator antenna) have been designed and investigated at terahertz spectrum i.e. 10 THz. Lower terahertz frequency band is useful for high data speed communication and upper band is used for optical sensors and free space wireless communications. Novelty in this work is to open up research in. terahertz. A unique geometry based dual band terahertz DRA with mathematical formulations has been proposed. The comprehensive analysis in terahertz regime have been worked out with S11, VSWR, radiation pattern and efficiency using conical TDRA. The conical terahertz DRA is designed at 10 THz frequency with 4.9 dBi, gain with bore sight radiation pattern. The equivalent circuit of conical terahertz DRA have been evaluated for dynamic impedance showing frequency dependence nature.

A Case of Teaching Modern Latvian

Numerous reviews of the language teaching subject show that, in spite of the impressive diversity of methods and approaches, certain basic ideas are repeated and reinterpreted, Recognition of the complexity and diversity of language learning contexts has led some to suggest that we have moved ‘beyond methods’ to a ‘postmethod’ condition (Kumaravadivelu 2002; Savignon 2007). It seems there is a big gap between CLT (communicative language teaching - one of the most popular methods today) as an approach and its implementation. This paper considers that dialogue, one of fundamentals of CLT, should be born within the free communication of learners who are taught to produce a monologue. The method of constructing lectures around good texts along with plenty of (grammar) drills is presented with the idea that such a method would help the learner to move rather speedily from the phase of interlanguage to the target language.

6G Cellular Networks and Connected Autonomous Vehicles

With 5G mobile communication systems having been commercially rolled out, research discussions on next generation mobile systems, that is, 6G, have started. On the other hand, vehicular technologies are also evolving rapidly, from connected vehicles called V2X (vehicle to everything) to autonomous vehicles to the combination of the two, that is, the networks of connected autonomous vehicles (CAV). How fast the evolution of these two areas will go hand-in-hand is of great importance, which is the focus of this article. After a brief overview of the technological evolution of V2X to CAV and 6G key technologies, this article explores two complementary research directions, namely, 6G for CAVs versus CAVs for 6G. The former investigates how various 6G key enablers, such as THz, cell free communication and artificial intelligence (AI), can be utilized to provide CAV mission-critical services. The latter discusses how CAVs can facilitate effective deployment and operation of 6G systems. This article attempts to investigate the interactions between the two technologies to spark more research efforts in these areas.

Dispersion-limited versus power-limited terahertz communication links using solid core subwavelength dielectric fibers

Terahertz (THz) band (0.1–10 THz) is the next frontier for ultra-high-speed communication systems. Currently, most of communications research in this spectral range is focused on wireless systems, while waveguide/fiber-based links have been less explored. Although free space communications have several advantages such as convenience in mobility for the end user, as well as easier multi-device interconnectivity in simple environments, fiber-based communications provide superior performance in certain short-range communication applications such as multi-device connectivity in complex geometrical environments (ex., intra-vehicle connectivity) and secure communications with low probability of eavesdropping, as well as secure signal delivery to hard-to-reach or highly protected environments. In this work, we present an in-depth experimental and numerical study of the short-range THz communications links that use subwavelength dielectric fibers for information transmission and define the main challenges and trade-offs in the link implementation. Particularly, we use air or foam-cladded polypropylene-core subwavelength dielectric THz fibers of various diameters (0.57–1.75 mm) to study link performance as a function of the link length of up to ∼ 10 m , and data bit rates of up to 6 Gbps at the carrier frequency of 128 GHz (2.34 mm wavelength). We find that depending on the fiber diameter, the quality of the transmitted signal is mostly limited either by the modal propagation loss or by the fiber velocity dispersion (GVD). An error-free transmission over 10 m is achieved for the bit rate of 4 Gbps using the fiber of smaller 0.57 mm diameter. Furthermore, since the fields of subwavelength fibers are weakly confined and extend deep into the air cladding, we study the modal field extent outside of the fiber core, as well as fiber bending loss. Finally, the power budget of the rod-in-air subwavelength THz fiber-based links is compared to that of free space communication links, and we demonstrate that fiber links offer an excellent solution for various short-range applications.

Experimental studies on the effects of fog and haze on free‐space optical link at 405 nm

AbstractFree‐space optics (FSO) is a perfect line of sight communication which is gaining a lot of popularity in the current research as it offers many advantages such as license free communication, high bandwidth, high speed, low bit error rate, and so on. Like the other communication technologies, FSO also suffers from adverse effects due to the climatic changes in the atmosphere. Some of the prominent effects that degrade the strength of the signal in free space are the fog, snow, haze, and rain. In this paper, the effects of fog and haze on the FSO link were investigated with the support of both simulated and experimental results. An experimental setup consisting of a single‐channel FSO system enclosed in a glass cabinet is used for generating the experimental results, and the simulation is carried out in OptiSystem using the Kim, Kruse, and Alnaboulsi prediction models. Results demonstrate that the simulated and experimental results follow the same pattern that as the intensity fog or the intensity of haze increases the received voltage levels decline.

Коммуникативная культура педагогов и родителей как условие воспитания свободы поведения ребенка

This article emphasizes the correlation between the communicative culture of adults (teachers and parents) and cultivation of freedom in preschool children’s behavior. The first part of the article is devoted to the pedagogical approaches to development of preschool children's communicative ways of speech communication. Among the methods of dialogical speech development there are communicative games, verbal didactic games with pair interaction and problematic situations. The communicative content of these games is realized through the child's implementation of certain game rules, which are perceived as rules of communication. This part discovers the effectiveness of playing out communicative situations as a method to master children’s culture of communication with their peers. The relations of full-fledged communication and cooperation require a significant renewal of children's life organization in kindergarten, and conditions for free communication, without any instructions, for the emancipation of the child's and the adult's personalities.&#x0D; The article shows the possibilities of children’s artistic activity for their dialogical communication with peers and teacher. It considers the features of organizing creative artistic activities when children create their own product (drawing, modeling, application, DIY) and wonder the opinion of other people – adults and children. This discussion differs from everyday dialogue in its content, since it has an artistic focus on the perception of art and creative activity. It is shown that communication during joint creativity of children arises due to an objective situation and a desire of children to cooperate, co-creation and empathy.&#x0D; The final part of the article is related to the content of experimental work to support the communicative culture of teachers and parents as the first transmitters of healthy communication experience to children. It examines domestic and foreign communication models that are most effective in working with teachers and parents of preschool children. The important elements of communication are explained accompanied by examples. Such support includes not only the level of verbal communication, but also a certain type of contact between an adult and a child: emotional, motional, gaming.

A trusted node-free eight-user metropolitan quantum communication network.

Quantum communication is rapidly gaining popularity due to its high security and technological maturity. However, most implementations are limited to just two communicating parties (users). Quantum communication networks aim to connect a multitude of users. Here, we present a fully connected quantum communication network on a city-wide scale without active switching or trusted nodes. We demonstrate simultaneous and secure connections between all 28 pairings of eight users. Our novel network topology is easily scalable to many users, allows traffic management features, and minimizes the infrastructure as well as the user hardware needed.
